Here's the proper way to delete the Windows.old and $Windows.BT folders: 1  Click Start and type in disk cleanup (no quotes). Wait for the Disk Cleanup utility to show up in the Start menu and click it. 2  A window will appear asking you which hard drive you want to clean up. Choose the C drive (which is default) and click OK.
The A-and B-type HCs are very similar in appearance in the rabbit retina too. Other species may have more than two types of horizontal cell and often these other types are concerned with color coding (see chapter on Horizontal cells by Perlman et al., webvision).
1 Describe the characteristics of light and color, outline the anatomy of the eye and its connections with the brain, and describe the process of transduction of visual information. 2  Describe the coding of visual information by photoreceptors and ganglion cells in the retina. The photoreceptors form synapses with bipolar cells, neurons whose two arms connect the shallowest and deepest layers of the retina. 2  In turn, these neurons form synapses with the ganglion cells, neurons whose axons travel through the optic nerves (the second cranial nerves) and carry visual information into the brain.
